Out of Band Configuration on Cisco ACI

Below are the Cisco ACI OOB configuration steps, we will use an example for illustration:


I- Assign static node management address

  • Navigate to: Tenant > Tenant mgmt > Node Management Addresses > Static Node Management Addresses

  • Configure APICs and switches OOB addresses:

Create on the action pane and click Create Static Node Management Addresses:


II- Provide an OOB contract on the Out of Band EPG

Navigate to: Tenant > Tenant mgmt > Node Management EPGs > Out-of-Band EPG default

In the Provided Out-of-Band Contract section, add a contract. We used default, but, It can more specific like an SSH, HTTP contract:


III- Define an External management network instance profile

Navigate To: Tenant > Tenant mgmt > External Management Network Instance Profiles

  • Create External Management Network Instance Profile:


IV- Consume the OOB Contract

Navigate To: Tenant > Tenant mgmt > External Management Network Instance Profiles > Ext_Management_Profile

In Consumed Out-of-Band Contracts, add the contract provided under the OOB EPG:



Note:

  • A External Management Network Instance Profile defines which External subnets can have access to ACI OOB management addresses.
  • By defaults all External subnets have OOB access (for initial setup purposes), but, you can limit it here.


Note

Also, you can define multiple External Management Network Instance Profiles. For each one, you will specify different External subnets that will access ACI OOB management and maybe apply different contract for each of them according to your requirements.



Summary

And because a picture is better than 1000 words, we can illustrate the OOB configuration in this simple diagram:
